Analysis of major methodological aspects of real time ultrasound examination of a male's vesical neck and urethra, known as video cysto-urethro-sonography (VCUS). Consideration must be given, when studying the posterior urethra, to the need of suitable vesical repletion, as well as to the existence of two likely limitations for conducting the test, such as: major anal stenosis, which would prevent introduction of the transrectal transducer; and inhibition of the voiding urge referred by some patients when they have to urinate in uncomfortable circumstances. As for the study of the anterior urethra, the most interesting technical items are: avoidance of air bubbles entering with the physiologic serum, which could artefact the examination; nonexertion of excessive compression on the urethra with the transducer, which may lead to false stenosis; and understanding that a major meatus stenosis may preclude test completion due to impossibility of introduction of Foley's catheter, necessary to obtain backward urethral distension with physiologic serum.
对男性膀胱颈部和尿道实时超声检查的主要方法学方面进行分析，即视频膀胱尿道超声检查（VCUS）。在研究后尿道时，必须考虑到膀胱适度充盈的必要性，以及进行该检查可能存在的两个局限性，例如：严重的肛门狭窄，这会妨碍经直肠探头的插入；以及一些患者在不舒适的情况下排尿时出现的排尿冲动抑制。至于前尿道的研究，最值得关注的技术要点包括：避免生理血清中混入气泡，以免影响检查结果；探头对尿道施加的压力不宜过大，否则可能导致假性狭窄；以及要明白，由于无法插入Foley导管（获取后尿道生理性扩张所必需），严重的尿道口狭窄可能会导致检查无法完成。
